Moisture, Hydrogen and Temperature Transmitter MHT410 Robust online key gas monitor for power transformers Compatible with all insulation liquids, including silicon oil. Secure your power transmission and distribution. The MHT410 helps prevent power outages and detect possible faults before they escalate. The end-result? Lower total cost of ownership and more secure operation. The MHT410 works in-situ, measuring directly from your transformer insulation liquid. Your gain? Reliable hydrogen trend reading as well as fast moisture data. Contact us Datasheet Continuous monitoring done right Continuously monitoring hydrogen and moisture levels is the first step in extending your transformers’ operational life — and implementing predictive maintenance practices. And when you pair the MHT410 with our robust Indigo520 transmitters giving you a readout both over a sleek WebUI, and the industrial-grade local graphical display — as well as powering the MHT410. 5-year warranty as standard The MHT410 is robust to the extreme. It’s why we are proud to offer it with a 5-year warranty as standard. So you can rely on it to keep going in the harshest of conditions. Key benefits Measure in-situ The MHT410 measures directly from all transformer insulation liquids — including silicon oil. No pumps or membranes are needed. Measure in real-time Get reliable hydrogen trend and moisture data in-real time. Get graphical with the Indigo520 Couple your MHT410 with an Indigo520 transmitter and you can monitor your transformer right from a laptop, or the local graphical display to see data trends on site. The Indigo520 can also power the MHT410 with a single-wire solution. Robust design, easy installation. The MHT410’s is made to stand up to the harshest conditions: isolated inputs and outputs, EMC tolerant, and IP66 metal housing. Supplied with standard DNP3.0 and MODBUS RTU communication protocols, it makes deployment within existing communications and SCADA networks easy. The MHT410 even includes three analog outputs for your SCADA interface. Continuous monitoring gives full visibility “It is completely different to follow the situation continuously than to take samples every now and then. After all, electricity networks can have quite exceptional switching situations – a transformer can have very high momentary loads and at other times be used only lightly.” – Operations Manager at Nivos Oy Installation images MHT410 installed on pipes X Installing MHT410 X Product documentation Datasheets User guides More in Docs.vaisala.com More downloads Order Form: MHT410 Order Form (100.71 KB) Customer case: TVO Nuclear Power Plant Monitors Transformer Condition Real-Time (139.06 KB) Technology Description: Moisture in oil technology description (143.19 KB) Technology Description: MHT410 DNP3 Device Profile Customer case: The Vaisala MHT410 Proves Itself to SEWA in the Arabian Desert and Wins an Award in the Process (1.43 MB) Pagination Next page ›› Product Resources eBook Moisture in Transformers Q&A eBook Filled with your actual questions answered by Vaisala's experts, this nearly 40-page eBook is a versatile manual for anyone whose business it is to maintain guard against and understand the effects of moisture in power transformers.
